Hello first time poster hereso please dont bash me to hard!

I have a baby ball that hates the heat no matter the temp. He move away from it no matter what. I use uth set at 90 deg. he will move from it so I turn it off and he is fine. I set it at 65 deg and he runs from it like I said no matter
the temp he just hates the heat.

I use boaphile cages 36x24x11.5 with an aspen bed 3 hides 2 water bowls
he eats fine but I'ts going to get cold soon any ideas?

Thanks!!!
